10yrs ago we looked at track built homes, like Lennar, in the Charleston SC market. We went with Brentwood - another track builder, but working on a smaller scale. I worked out OK - but I can tell this house WILL NOT last a lifetime. They DO NOT build them like they used to. As a matter of fact, one of my neighbors is a licensed GC; the track builder brought them in from Texas to do QC and guarantee work.. until the bottom fell out. He does lots of private small jobs now - bathrooms, porches, kitchens - using some of the same subs that worked for the track builder. Most of his work comes 'word of mouth'.
In SC, you can go to the SC Labor License and Regulation site - and search for LICENSED General Contractors, specialty (electrical, plumbing, framing, etc.....). You can find individuals and large GCs. You can try Lowes or Home Depot - ask at the Pro Desk, check Craig's List (use caution & get references), and drive around through some of the areas that you might want to live in and stop on a job site to look at the quality in the field. Some small private GCs will build a nice custom house, and have a 'spec house' or two that they are working on at the same time.
All of the above posts are very true, and @NCFJ is spot on: rent something for now, find a lot, hire an independent GC to build what you want. The market should still be saturated, even in Charlotte, with existing new homes that you could negotiate to rent in lieu of buying - at least the owner has someone making the mortgage payment.
If you're just looking for a house - don't worry, find something that fits, clean it up, paint it and flip it. If you're looking for a home - LOCATION, LOCATION, LOCATION (not to mention foundations, framing, lot size, and mature trees...).
Best of luck - and make sure that you have room for your Cruiser !
